Description Jeff Layton 2010-08-25 10:53:19 UTC

Summary:

SELinux is preventing /usr/bin/gconftool-2 "create" access on
linc-92e-0-1a9593a234557.

Detailed Description:

SELinux denied access requested by gconftool-2. It is not expected that this
access is required by gconftool-2 and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2010-08-25 12:51:11 UTC

Dominick 

Should I just add

manage_sock_files_pattern(telepathy_msn_t, telepathy_msn_tmp_t, telepathy_msn_tmp_t)
userdom_user_tmp_filetrans(telepathy_msn_t, telepathy_msn_tmp_t, { dir file sock_file})

Comment 2 Jeff Layton 2010-08-25 13:18:03 UTC

There's another related warning too (setattr instead of create):

node=corrin.poochiereds.net type=AVC msg=audit(1282742366.961:616): avc: denied { setattr } for pid=6196 comm="gconftool-2" name="orbit-jlayton" dev=sda3 ino=1379483 scontext=unconfined_u:unconfined_r:telepathy_msn_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_tmp_t:s0 tclass=dir

Comment 3 Dominick Grift 2010-08-25 13:34:49 UTC

I think:

files_tmp_filetrans(telepathy_msn_t, telepathy_msn_t, { dir file sock_file })

and:

userdom_usr_tmp_filetrans(telepathy_msn_t, telepathy_msn_t, sockfile)

the setattr or orbit can be dontaudited ( that is what i do)

Comment 4 Dominick Grift 2010-08-25 13:36:36 UTC

so it creates a sock_file in /tmp/orbit-USER, plus it creates a dir in /tmp and puts a sock_file in there atleast (and i believe also a file)

Comment 5 Dominick Grift 2010-08-25 13:40:10 UTC

I made some syntax errors in my examples above but i hope you get the idea

dir file sock file in /tmp (tmp_t)
sock_file in /tmp/orbit-USER (user_tmp_t) 
do not audit attempts to set attributes of user temporary directories. (user_tmp_t/orbit-USER)

Comment 6 Dominick Grift 2010-08-25 13:51:14 UTC

Basically user apps only create sock_files in /tmp/orbit-USER and they try to set attributes of /tmp/orbit-USER (that what all gnome user apps do)

manage_sock_files_pattern(telepathy_msn_t, telepathy_msn_tmp_t, telepathy_msn_tmp_t)
userdom_user_tmp_filetrans(telepathy_msn_t, telepathy_msn_tmp_t, sock_file)
userdom_dontaudit_setattr_tmp_dir(telepathy_msn_t)

and besides that:

manage_dirs_pattern(telepathy_msn_t, telepathy_msn_tmp_t, telepathy_msn_tmp_t)
manage_files_pattern(telepathy_msn_t, telepathy_msn_tmp_t, telepathy_msn_tmp_t)
manage_sock_files_pattern(telepathy_msn_t, telepathy_msn_tmp_t, telepathy_msn_tmp_t)
files_tmp_filetrans(telepathy_msn_t, telepathy_msn_tmp_t, { dir file sock_file })

It creates this for file sharing with butterfly.
